Abstract
Apparatus for severing a plurality of plies of a thermoplastic material and sealing the severed margins thereof is provided. The apparatus comprises a hot-wire element proximate the thermoplastic material for severing and sealing the thermoplastic material. The apparatus further comprises a chamber or manifold for enveloping the hot-wire element in an inert atmosphere which impinges on a proximal portion of the thermoplastic material to be severed and sealed. The apparatus further comprises an actuating mechanism, associated with the hot-wire element, for translating the hot-wire element toward the proximal portion of the thermoplastic material. As a result, the hot-wire element severs the plurality of plies and seals the severed margins thereof so that the severed margins are enveloped by the inert atmosphere impinging on the thermoplastic material.
